How time flies! Thinking back to the past three years, I thought my school life was busy but wonderful, and I always felt happy and fulfilled every day.First, my school was beautiful. There were bright classrooms and a big clean playground. We studied and played happily there every day. Second, my teachers were kind and patient. They taught me lots of useful knowledge and always helped me when I was in trouble. My classmates were friendly and helpful, too. We studied together and shared happiness and sadness with each other.
